Direction-of-Arrival Estimation in a Clustered Channel Model

In this paper, we study the performance of the MUltiple SIgnal Classification (MUSIC) direction-of-arrival (DoA) estimation algorithm in a clustered channel model. We examine the effect of angular spread on the estimation accuracy of the MUSIC algorithm. Simulation result shows that the performance of the MUSIC algorithm degrades as the angular spread increases. Furthermore, an experimental study is performed in an anechoic chamber to evaluate the performance of DoA estimation using a single reconfigurable antenna element known as Composite Right/Left Handed (CRLH) Leaky-Wave (LW) antenna that offers a high level of directivity with electronically controllable radiation patterns. Experimental results show that the DoA estimation technique succeeded in estimating the DoA using a single antenna element.
